Netscape
var xmldoc = document.implementation.createDocument()
※document.implementationプロパティは、DOMImplementaion
オブジェクトへの参照。
※DOMImplementationオブジェクトのcreateDocumentメソッド
はXMLのDocumentオブジェクトを生成する。
※Firefoxで、alert(xmldoc)とすると「XMLDocument」と
表示される。
IE
var xmldoc = ActiveXObject("MSXML2.DOMDocument)
２．xmlファイルを取り込む。
xmldoc.async = false;
xmldoc.load("sample.xml");
３．取り込んだxmlファイルを操作する
var tags = xmldoc.getElementsByTagName("items");
for (var i=0; i<tags.length; i++){
tags[i].getElementsByTagName("no")[0].firstChild.nodeValue;
tags[i].getElementsByTagName("title")[0].firstChild.nodeValue;
tags[i].getElementsByTagName("link")[0].firstChild.nodeValue;
}
